Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing equipment, and in particular to a gear deburring device and method. Background Art

[0002] During the gear manufacturing process, machine tool cutting may cause large burrs on both ends of the gear. Removing burrs is crucial to ensuring the flatness and smoothness of the gear surface. This can not only avoid problems such as tooth jamming and tooth skipping, ensure the smooth operation of the gear, but also improve transmission efficiency, reduce friction and energy loss, and extend the service life of the gear.

[0003] At present, the common treatment method is to fix the gear and drive it to rotate, use a rotating polishing wheel to grind and polish close to the burr, and sometimes use an angle grinder to handle it together. However, since the burrs are mainly concentrated on both sides of the teeth and the depressions between the teeth, using a polishing wheel with a larger coverage area may not only cause unnecessary gear loss, but also reduce the processing accuracy and overall finish. In addition, when completing the grinding of one tooth and turning to the next tooth, if you do not retreat first and then adjust the position, the depression may hinder the entry of the grinding tool, resulting in a dead angle when passing through the concave area, resulting in insufficient grinding; at the same time, continuous grinding will also accelerate the wear of the polishing wheel and affect the treatment effect of the protruding tooth surface.

[0004] In view of the above problems, it is necessary to design a gear deburring device and method that can further reduce the loss of the gear itself while effectively ensuring the overall smoothness of the tooth surface. The device aims to accurately locate and process burrs, avoid unnecessary damage to non-target areas, and ensure that each tooth can be polished evenly and thoroughly. In this way, the quality and performance of the gear can be improved, and production efficiency can be improved and costs can be reduced. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment: A gear deburring device, such as Figure 1-Figure 9 As shown, including: The bottom frame 1 is a hollow frame; Two vertical plates 2 are fixedly arranged on the left and right sides of the base frame 1, respectively. The left vertical plate 2 is provided with an insertion rod 21 for placing the gear body 100; The movable seat 3 slides on the front side of the base frame 1. The movable seat 3 can slide forward and backward along the base frame 1. A bidirectional screw rod 35 driven by a driving assembly rotates between the left and right inner walls of the movable seat 3. The driving assembly is installed on the movable seat 3. A movable plate 37 slides symmetrically on the left and right sides of the movable seat 3. The front ends of the two movable plates 37 are respectively threadedly connected with one side of the bidirectional screw rod 35. When the driving assembly causes the bidirectional screw rod 35 to rotate, according to the operating principle of the thread, the bidirectional screw rod 35 will drive the movable plates 37 on both sides to slide toward or away from each other along the axial direction of the screw rod, thereby realizing the expansion or approaching action between the two movable plates 37, and a driving gear 38 for driving the gear body 100 to rotate is installed between the movable plates 37 on both sides; Two cutting knives 4 are respectively arranged at the rear ends of the two moving plates 37, and are specially used to process the large burrs generated on both sides of the teeth of the gear body 100. At the same time, combined with the design of the movable plate 37 that can expand or close, the cutting knives 4 can flexibly adapt to the processing requirements of gears of different sizes, thereby expanding the application range and flexibility of the device; Two rodless cylinders 5 are symmetrically installed on the rear side of the base frame 1. A moving frame 51 is arranged between the sliders of the rodless cylinders 5. The moving frame 51 can be moved in the front-rear direction by the drive of the rodless cylinders 5. There are two semicircular frames 52 rotating in an upper and lower interval manner between the left and right sides of the moving frame 51. A wire brush 54 driven by a corresponding motor 3 53 rotates in the semicircular frame 52. The motor 3 53 is respectively arranged on the semicircular frames 52 on both sides, and the output end of the motor 3 53 is respectively connected to the shaft end of the wire brush 54 on the same semicircular frame 52. By adjusting the angle of the semicircular frame 52, the direction of the wire brush 54 can be changed so that it can penetrate into the depression between the teeth of the gear body 100 and effectively remove the burrs in the difficult-to-reach position; Specifically, under the action of the driving gear 38, the gear body 100 is rotated, which helps to adjust the specific position of burr removal. First, by the cutting knives 4 on both sides closely fitting the tooth side of the gear body 100, the large burrs on both sides of each tooth can be preliminarily scraped off to ensure that the surface of the gear body 100 reaches basic flatness. Next, in order to further ensure the thoroughness of the burr treatment, it is necessary to take into account the treatment of the built-in burrs between the teeth of the gear body 100. The rodless cylinder 5 is used to accurately adjust the relative position between the wire brush 54 and the gear body 100, and with the help of the angle adjustment function of the semicircular frame 52, the wire brush 54 can accurately enter the recess between the teeth of the gear body 100. Then the motor 3 53 drives the wire brush 54 to rotate to effectively remove the burrs between the teeth, thereby achieving deburring within a specific range. This step-by-step treatment method not only avoids unnecessary material loss of the gear body 100, but also further ensures the smoothness of the tooth surface after treatment.

[0032] Two groups of pushing rods 6 are symmetrically arranged on the moving frame 51. Two pushing rods 6 are arranged on each side at intervals. The pushing rods 6 are designed to be bent, and a convex structure extending backward is arranged at its end. A moving rod 61 is slidably penetrated on the vertical plate 2. The moving rod 61 is for sliding operation in the front-back direction. A buckle plate 62 is arranged at the end of the moving rod 61 to contact and cooperate with the pushing rod 6 on the same side. The buckle plate 62 is provided with a card groove with an interval of up and down, and the card groove can be connected with the protrusion of the pushing rod 6 at the corresponding position. When the two are in contact, the pushing rod 6 and the moving rod 61 on the same side can work together; in addition, an extension end is provided on the front side of the vertical plate 2, and a guide frame 63 is slidably provided on the extension ends on both sides. The guide frame 63 can realize sliding in the left and right directions. A pulling component is arranged between the guide frame 63 and the moving rod 61 on the same side to ensure that the moving rod 61 and the guide frame 63 on the same side can move synchronously; Motor four 7 is installed on the guide frames 63 on both sides, and a grinding rod 74 is installed on the output end of motor four 7. The grinding rod 74 is specially used to further refine the tooth surface of the gear body 100 to completely remove the burrs remaining on the surface and improve the smoothness of the tooth surface.

[0033] like Figure 2 and Figure 3 As shown, the driving assembly includes a motor 33, a motor 33 with an output end facing downward is installed on the moving seat 3, a worm 34 is connected to the output end of the motor 33, and a worm wheel 36 meshing with the worm 34 is arranged in the middle of the bidirectional lead screw 35. When the motor 33 drives the worm 34 to rotate, the transmission action of the worm wheel 36 drives the bidirectional lead screw 35 to rotate.

[0034] like Figure 8 As shown, the pulling assembly includes an elastic member 64, and an elastic member 64 is arranged between the guide frame 63 and the corresponding extension end. In the present embodiment, the elastic member 64 is a spring, which can provide the necessary elastic force for the guide frame 63 to reset, and a group of pulleys 65 arranged front and back are rotated in the extension end, and a pull rope 66 passing through the corresponding pulley 65 is arranged between the guide frame 63 and the moving rod 61 on the same side. When the moving frame 51 is away from the gear body 100, the end of the push rod 6 is engaged with the corresponding buckle plate 62, thereby pulling the connected moving rod 61, and with the help of the pull rope 66, the guide frame 63 and the grinding rod 74 are further driven away from the gear body 100. At this time, the elastic member 64 is deformed to store energy; when it is needed to be reset later, by driving the moving frame 51 close to the gear body 100, and under the coordinated action of the pull rope 66 and the elastic member 64, the guide frame 63 can be close to the gear body 100 again to realize the linkage operation.

[0035] Specifically, to ensure the precise removal of burrs in each area of the gear body 100 that requires burr treatment, first, a cutting tool 4 is used to scrape off the larger burrs on both sides of the teeth. To further process the recesses between the teeth and the fine residual burrs on the tooth surface, a wire brush 54 and a grinding rod 74 are specially configured to work together. The guide frame 63 and the moving rod 61 are connected by a pull rope 66 to achieve the synchronous movement and operation of the wire brush 54 and the grinding rod 74, enabling both to process the target area simultaneously and disengage synchronously, that is, to retreat appropriately after processing one area to better adjust the position and then process the next area, ensuring the accuracy and efficiency of the processing process, and thus more effectively guaranteeing the burr removal effect and overall smoothness of the gear body 100.

[0036] As Figure 2 and Figure 3 shown, it further includes a turntable 372. Turntables 372 are rotatably installed at the rear ends of both sides of the moving plate 37. The driving gear 38 is located between the two turntables 372, and the driving gear 38 is key-connected to the shaft ends of the turntables 372 on both sides. A second motor 371 with an output end connected to the corresponding turntable 372 is installed on one side vertical plate 2. The second motor 371 drives the turntable 372 to rotate, thereby driving the driving gear 38 to rotate synchronously, ensuring the stable rotation of the gear body 100 during the processing process. And by adjusting the positions between the moving plates 37, the driving gear 38 can be quickly disassembled and assembled, so as to flexibly meet the processing requirements of gear bodies 100 of different specifications, ensuring that the device has good adaptability.

[0037] As Figure 6 and Figure 7 shown, it further includes a grip rod 55. A grip rod 55 is rotatably installed on one side of the moving frame 51. A second worm 56 is arranged on the grip rod 55. A second worm gear 57 meshing with the second worm 56 is arranged at the shaft end of one side semi-circular frame 52. Transmission gears 58 are arranged at the shaft ends on the other sides of the two semi-circular frames 52, and the transmission gears 58 on both sides mesh with each other. When the angular position of the wire brush 54 needs to be adjusted, the second worm 56 is driven to rotate by operating the grip rod 55, and then the second worm gear 57 is driven to rotate, enabling the corresponding semi-circular frame 52 to achieve angular adjustment. At the same time, the transmission gears 58 on the two semi-circular frames 52 mesh with each other, ensuring that when one semi-circular frame 52 changes its angle due to the rotation of the second worm gear 57, the other semi-circular frame 52 can also be adjusted synchronously by a corresponding amplitude, maintaining the balance of the structure operation, so as to ensure that the bilateral wire brushes 54 can process the gear body 100 at an appropriate angle. At the same time, the second worm 56 and the second worm gear 57 have a self-locking function, which can lock the position of the adjusted semi-circular frame 52 to ensure the stability during the operation process.

[0038] As Fig. 9As shown, it also includes an assembly frame 71, and the output end of the motor 47 is connected with the assembly frame 71 through a coupling. The left and right sides of the assembly frame 71 are slidably provided with a card plate 72 that is engaged with the corresponding grinding rod 74. An elastic member 3 73 is arranged between the card plates 72 of the same assembly frame 71. In this embodiment, the elastic member 3 73 is a spring, and its function is to provide the necessary elastic force to realize the automatic reset of the card plate 72. A positioning wheel frame 75 is arranged on the side of the guide frame 63 facing the gear body 100. When the guide frame 63 approaches the gear body 100, the positioning wheel frame 75 will first contact the surface of the gear body 100, thereby adjusting the position of the grinding rod 74 relative to the gear body 100. In addition, considering the gears of different models and sizes, in order to ensure the adaptability of the grinding operation, the card plate 72 can be manually pinched to quickly release the restriction on the grinding rod 74, so as to realize the rapid disassembly and replacement of the grinding rod 74, so as to facilitate the subsequent adaptive assembly for the grinding needs of different forms of gears, and improve the operational flexibility.

[0039] like Figure 1 and Fig.10 As shown, it also includes a mounting plate 8. A group of mounting plates 8 spaced apart from each other are arranged on the top of the vertical plate 2. A blowing frame 81 for blowing away waste chips is arranged between the mounting plates 8 in the same group. The air outlet of the blowing frame 81 faces the gear body 100. The bottom of the blowing frame 81 is connected to an air pipe 82. The air pipe 82 is connected to an external fan, and the fan can blow the airflow into the corresponding blowing frame 81 to ensure that the airflow can be accurately blown to the gear body 100 being processed, thereby quickly removing the waste chips generated during the processing, helping to keep the working environment clean and tidy, and reducing the impact of waste chip accumulation on the processing quality.

[0040] like Figure 2 As shown, it also includes a fixing rod 31, and the fixing rod 31 is slidably inserted between the left and right sides of the movable seat 3. The fixing rod 31 is an inverted U-shaped structure, and toothed blocks are arranged at both ends of the fixing rod 31. A card rack 32 is respectively arranged on the left and right sides of the front part of the base frame 1. The card rack 32 is adapted to and connected with the toothed blocks at the same side ends of the fixing rod 31, thereby improving the stability of the position of the movable seat 3 and reducing unnecessary shaking and displacement.

[0041] like Figure 4 As shown, it also includes a guide rod 41. The upper and lower sides of the rear end of the movable plate 37 are fixedly provided with guide rods 41. A holder 42 that is plugged in and matched with the cutting tool 4 on the same side is slidably provided on the guide rod 41. An elastic member 43 is provided between the holder 42 and the end of the corresponding guide rod 41. In the present embodiment, the elastic member 43 is a spring, which provides the necessary elastic force to ensure that the corresponding holder 42 can automatically reset. At the same time, due to the plug-in connection between the holder 42 and the cutting tool 4, the cutting tool 4 can be flexibly replaced as needed to meet the processing requirements of gear bodies 100 of different shapes.

[0042] Based on the above gear deburring device, a gear deburring method specifically includes the following steps: S1. First, insert the gear body 100 onto the insertion rod 21, start the motor 1 33, drive the bidirectional screw 35 to rotate to adjust the position of the moving plate 37, thereby changing the spacing between the rotating disks 372, and then insert the driving gear 38 between the shaft ends of the two rotating disks 372, so that the driving gear 38 is meshed with the gear body 100; S2. According to the specifications and shape requirements of the gear body 100, replace the appropriate cutting blade 4 and grinding rod 74. At the same time, by holding the grip rod 55 and rotating the worm 56, the worm 56 is meshed with the worm wheel 57, driving the semicircular frame 52 and its upper parts to rotate and tilt synchronously. Under the meshing action of the transmission gear 58, the two semicircular frames 52 coordinately adjust their positions until the wire brushes 54 on both sides are aligned with the recessed parts between the teeth of the gear body 100. S3, ensure that the grinding rod 74 and the wire brush 54 are separated from the gear body 100, and at the same time, the push rod 6 and the buckle plate 62 are in a locked state; start the second motor 371, drive the driving gear 38 to rotate and mesh with the gear body 100, so that the gear body 100 rotates, so that under the action of the cutting knives 4 on both sides, the large burrs on both sides of the gear teeth of the gear body 100 are scraped off; S4. After the large burr treatment is completed, the rodless cylinder 5 is started to drive the moving frame 51 and its upper parts to move as a whole toward the gear body 100, so that the two wire brushes 54 fit into the corresponding inter-tooth depressions. At this time, the push rod 6 is separated from the buckle plate 62. Under the action of the pull rope 66, the position of the guide frame 63 is adjusted in coordination with the movement of the moving rod 61, so that the grinding rod 74 fits into the surface of the gear body 100. Then, the motor three 53 and the motor four 7 are started to drive the wire brush 54 and the grinding rod 74 to rotate respectively, so as to further remove the inter-tooth depressions and burrs on the tooth surface of the gear body 100. S5. After the grinding of the current position is completed, the rodless cylinder 5 is started again to move the wire brush 54 away from the gear body 100, the push rod 6 is re-engaged with the buckle plate 62, and the moving rod 61 is pulled. Under the coordinated action of the pull rope 66, the grinding rod 74 is synchronously moved away from the gear body 100, and then the motor 2 371 is started to drive the driving gear 38 to rotate and mesh with the gear body 100, so that the gear body 100 rotates and changes position, and then the wire brush 54 and the grinding rod 74 are reset and attached to the gear body 100 to grind the burr part after displacement, and the above operation is repeated until all the inter-tooth depressions and tooth surfaces of the gear body 100 are polished; S6.
